Inter- and Intraspecific Variation in Drosophila Genes with Sex-Biased Expression
Figure 7
Gene expression variation within a population, between populations, and between species. Shown are the percentages of male-biased (M), unbiased (U), and female-biased (F) genes that show significant expression variation within a Zimbabwe population of D. melanogaster, between a Zimbabwe and a European population of D. melanogaster and between D. melanogaster and D. simulans. Expression variation was measured separately in males (a) and females (b). Data are from Hutter et al. [31], Müller et al. [32], and Ranz et al. [33]. Asterisks indicate significant differences from unbiased genes within the same comparison, as determined by Fisher’s exact test. *, **.
